Renardo requires SuperCollider installed and bootable separately before it can produce sound

Renardo is a Python layer that sends OSC messages to a running SuperCollider server (scsynth). Installing Renardo alone produces no sound — SuperCollider must also be installed via the official installer (Windows/macOS) or package manager (Linux) and its server booted with s.boot or Server.default.boot. On Linux, JACK or PipeWire-JACK is additionally required for audio routing. After SuperCollider boots successfully (no errors in the post window, SinOsc.ar().play audible), Renardo connects automatically when launched. A common beginner error is launching Renardo before booting SuperCollider, resulting in silence.

Examples

Verify SuperCollider works before connecting Renardo:

s.boot
{ SinOsc.ar() }.play;

Then launch Renardo: renardo or python -m renardo

Assessment

A learner installs Renardo but hears nothing. List three things to check, in order. Why must SuperCollider be booted first?
